We and our allies have to do something now. No more pussy foot diplomacy and backroom games that only result in the North Korea backing out and wanting more economic aid from us. The only way you beat a midget size bully is to pound him into submission. He doesn't understand anything else besides force. Yes, a war with NK will cost lives but if we wait any longer, a) we'll look very weak b) China will look strong and c) they'll give their nukes to terrorists, which will cost us hundreds of thousands of lives.
